States Race to Help Renewables Beat the Tax Credit Clock

Trump’s One Big Beautiful Bill Act put new expiration dates on clean energy tax credits for business and consumers, raising the cost of climate action. Now some states are rushing to accelerate renewable energy projects and get as many underway as possible before the new deadlines take effect.

The new law requires wind and solar developers to start construction by the end of this year in order to claim the full investment or production tax credits under the rules established by the Inflation Reduction Act. They’ll then have at least four years to get their project online.

Those that miss the end-of-year deadline will have another six months, until July 4, 2026, to start construction, but will have to meet complicated sourcing restrictions on materials from China. Any projects that get off the ground after that date will face a severely abbreviated schedule — they’ll have to be completed by the end of 2027 to qualify, an all-but-impossibly short construction timeline.

Adding even more urgency to the time crunch, President Trump has directed the Treasury Department to revise the rules that define what it means to “start construction.” Historically, a developer could start construction simply by purchasing key pieces of equipment. But Trump’s order called for “preventing the artificial acceleration or manipulation of eligibility and by restricting the use of broad safe harbors unless a substantial portion of a subject facility has been built,” an ominous sign for those racing to meet already accelerated deadlines.

While the changes won’t suppress adoption of these technologies entirely, they will slow deployment and make renewable energy more expensive than it otherwise would have been. Some states that have clean energy goals are trying to lock in as much subsidized generation as they can to lessen the blow.

There are two ways states can meet the moment, Justin Backal Balik, the state program director at the nonprofit Evergreen Action, told me. Right now, many are trying to address the immediate crisis by helping to usher shovel-ready projects through regulatory processes. But states should also be thinking about how to make projects more economical after the tax credits expire, Balik said. “States can play a role in tilting the scale slightly back in the direction of some of the projects being financially viable,” he said, “even understanding that they’re not going to be able to make up all of the lost ground the incentives provided.”

In the first category, Colorado Governor Jared Polis sent a letter last week to utilities and independent power producers in the state committing to use “all of the Colorado State Government to prioritize deployment of clean energy projects.”

“Getting this right is of critical importance to Colorado ratepayers,” Polis wrote. The nonprofit research group Energy Innovation estimates that household energy expenses in Colorado could be $170 higher in 2030 than they would have been because of OBBB, and $310 higher in 2035. “The goal is to integrate maximal clean energy by securing as much cost-effective electric generation under construction or placed in service as soon as possible, along with any necessary electricity balancing resources and supporting infrastructure,” Polis continued.

As for how he plans to do that, he said the state would work to “eliminate administrative barriers and bottlenecks” for renewable energy, promising faster state reviews for permits. It will also “facilitate the pre-purchase of project equipment,” since purchasing equipment is one of the key steps developers can take to meet the tax credit deadlines.

Other states are looking to quickly secure new contracts for renewable energy. In mid-July, two weeks after the reconciliation bill became law, utility regulators in Maine moved to rapidly procure nearly 1,600 gigawatt-hours of wind and solar — for context, that’s about 13% of the total energy the state currently generates. They gave developers just two weeks to submit proposals, and will prioritize projects sited on agricultural land that has been contaminated with per- and polyfluoroalkyl substances, the chemicals known as PFAS. (When asked how many applications had been submitted, the Maine Public Utilities Commission said it doesn't share that information prior to project selection.)

Connecticut’s Department of Energy and Environmental Protection is eyeing a similar move. During a public webinar in late July, the agency said it was considering an accelerated procurement of zero-carbon resources “before the tax increase takes effect.” The office put out a request for information to renewable energy developers the next day to see if there were any projects ready to go that would qualify for the tax credits. Officials also encouraged developers to contact the agency’s concierge permit assistance services if they are worried about getting their permits on time for tax credit eligibility. Katie Dykes, the agency’s commissioner, said during the presentation that the concierge will engage with permit staff to make sure there aren’t incomplete or missing documents and to “ensure smooth and efficient review of projects.”

New York’s energy office is planning to do another round of procurement in September, the outlet New York Focus has reported, although the solicitation is late — it had originally been scheduled for June. The state has more than two dozen projects in the pipeline that are permitted but haven’t yet started construction, according to Focus, and some of them are waiting to secure contracts with the state.

Others are simply held up by the web of approvals New York requires, but better coordination between New York agencies may be in the works. “I assembled my team immediately and we are trying to do everything we can to expedite those [renewable energy projects] that are already in the pipeline to get those the approvals they need to move ahead,” Governor Kathy Hochul said during a rally at the State University of New York’s Niagara campus last week. The state’s energy research and development agency has formed a team “to help commercial projects quickly troubleshoot and advance towards construction,” according to the nonprofit Evergreen Action. (The agency did not respond to a request for more information about the effort.)

States and local governments are also planning to ramp up marketing of the consumer-based credits that are set to expire. Colorado, for example, launched a new “Energy Savings Navigator” tool to help residents identify all of the rebate, tax credit, and energy bill assistance programs they may be eligible for.

Consumers have even less time to act than wind and solar developers. Discounts for new, used, and leased electric vehicles will end in less than two months, on September 30. Homeowners must install solar panels, batteries, heat pumps, and any other clean energy or efficiency upgrades before the end of this year to qualify for tax credits.

Many states offer additional incentives for these technologies, and some are re-tooling their programs to stretch the funding. Connecticut saw a rush of demand for its electric vehicle rebate program, CHEAPR, after the OBBB passed. Officials decided to slash the subsidy from $1,500 to $500 as of August 1, and will re-assess the program in the fall. “The budget that we have for the CHEAPR program is finite,” Dykes said during the July webinar. “We are trying to be good stewards of those dollars in light of the extraordinary demand for EVs, so that after October 1 we have the best chance to be able to provide an enhanced rebate, to lessen the significant drop in the total level of incentives that are available for electric vehicles.”

As far as trying to address the longer-term challenges for renewables, Balik highlighted Pennsylvania Governor Josh Shapiro’s proposal to streamline energy siting decisions by passing them through a new state board. “One of the big things states can do is siting reform because local opposition and lawsuits that drag forever are a big drag on costs,” Balik told me.

A bill that would create a Reliable Energy Siting and Electric Transition Board, or RESET Board, is currently in the Pennsylvania legislature. (New York State took similar steps to establish a renewable siting office to speed up deployment in 2020, though so far it’s still taking an average of three years to permit projects, down from four to five years prior to the office’s establishment.) Connecticut officials also discussed looking at ways to reduce the “soft costs” of permitting and environmental reviews during the July webinar.

Balik added that state green banks can also play a role in helping projects secure more favorable financing. Their capacity to do so will be significantly higher if the courts force the federal government to administer the Greenhouse Gas Reduction Fund.

When it comes to speeding up renewable energy deployment, there’s at least one big obstacle that governors have little control over. Wind and solar projects need approval from regional transmission operators, the independent bodies that oversee the transmission and distribution of power, to connect to the grid — a notoriously slow process. The lag is especially long in the PJM Interconnection, which governs the grid for 13 mid-Atlantic States, and has generally favored natural gas over renewables. But governors are starting to turn up the pressure on PJM to do better. In mid July, Shapiro and nine other governors demanded PJM give states more of a say in the process by allowing them to propose candidates for two of PJM’s board seats.

“Can we use this moment of crisis to really impress the urgency of getting some of these other things done — like siting reforms, like interconnection queue fixes, that are all part of the economics of projects,” Balik asked. These steps may help, but lengthy federal permitting processes remain a hurdle. While permitting reform is a major bipartisan priority in Congress, as my colleague Matthew Zeitlin wrote recently, a deal that’s good for renewables might require an about-face from the president on wind and solar.
